MOHLD FOR CASTING JOURNAL-BOX LININGS.

SPEGIFIGATION forming part of Letters Patent N o. 683,824, dated October 1, 1901.

Application filed March 11, 1901. Serial No. 50,658. (No model.)

To all whom, t may' concern:

Be it known that I, FRED M. WELD, a citizen of the United States, and a resident of Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Molds for Casting Journal-Box Linings, of which the following 'is a specification.

This invention has reference to an improvement in molds for casting the linings into journal-boxes.

Journal-boxes are usually lined with Babbitt or other compound metal linings. It is desirable to cast these linings into the journal-boxes so perfect and complete Ithat little or no nishing is required.

The object of this invention is to facilitate thelcasting of the linings into the journalboxes; and to this end the invention consists in the peculiar and novelconstruction and the combination of the parts whereby linings may be cast into the j ournal-boxes complete with the required thickness of the projecting end flange, as will be more fully set forth hereinafter.

Figure 1 is a front view of my improved mold. Fig. 2 is a side view of the same with' i a' the back plate of the mold. The brackets a2 project from the rea-r of the back plate a. The core b is secured to the front of the back plate a by the screws b b'. The half c of the journal-box into which the lining is to be cast has usually on its lower end the flange c' and bears along its longitudinal edges against the front face of the back plate a', one edge bearing against the stopplate c2, secured to the face of the back plate. The half of the journal-box when adj usted to the stopplate c2 is-secured by the clamping-lever d, hinged on one side to a bracket and secured by engaging with the ratchet-teeth of the arm CZ. The space between the lower end of the half c and the base a is closed by the band d2, of flexible sheet metal. The band d2 is secured at one end to the back plate a. It extends around the flange c' and has the other end secured to the lever d3. A strong spiral spring d*1 is interposed between the band d2 and the lever d3. When the band d2 is tightly stretched, the lever is secured by cngaging with a fixed ratchet a4, as is shown in Fig. 2. A funnel-shaped gate e is formed partly in the core and partly in the piece c?, provided with the handle c4. The piece c3 closely fits the core b, except at the portion forming the gate e.

In casting the piece c3 is placed onto the half of the journal-box and against the core. When the casting is completed, the lever d3 and the clamping-lever d are released. The half c of the journal-box is now pushed outward by the camsff, acting on the posts f'f, which extend through the back plate a and bear against the edges of the half of the j ournal-box, as is shown in Fig. 3. The cams ff are secured to the shafts f2f2, journaled in the brackets a2 a2, and are operated by the lever f3, secured to the lower shaft f2, and the lever f4, secured to the upper shaft f2 and connected with the lever f3, so that all the cams will operate simultaneously to move the journal-box, now provided with a lining, away from the core. A spring f5 is coiled on each shaft f2 to return the cams f to normal position. Only the slight fin of the gate e requires to be broken off to complete the journal-box. The core b may be removed and replaced by another core and the stopplate c2 replaced by another when journalboXes of different dimensions require to be lined.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A mold for casting the linings into journal-boxes having a base and back plate, a removable core secured to the back plate, means for securing a half of a journal-box against the face of the back plate, and means for loosening the box after casting the lining comprising a plurality of shafts, a lever connected to the shafts for operating them, cams on the shafts, andv posts extending through the back plate, as described.

2. In a mold for casting the linings into j carnal-boxes, the combination with the base, the back plate and the core secured to the back plate, of a stop-plate for gaging the po- IOO sition of the journal-b0x, a clamping-lever for securing the box to the back plate, a ilexible band for closing the space between the end of the box and the base-plate, a detachable gate-piece, and means for loosening the box after casting the lining comprising a plurality of shafts, a lever connected to the shafts for operating them, cams on the shafts, and stops extending through the back plate, as described.
